A sample from this course

One topic, as StudyPath teaches it.

Objectives;

The objectives of studying metals focus on understanding what metals are, why they are important in science and industry, and how their structure relates to their properties and uses. For examination purposes, students must master the broad aims of metal study: identification, extraction, processing, property evaluation, and proper application of metals in real-life situations.
